`InarLvvaiz SAFETY APPLIANCE.

To all whomi't may concern:

Be it known `that I, CHARLY A. Tnoiis Liann, a citizen of the UnitedStates,.and a resident of thecity of Berwyn, county of Cook, and Stateof Illinois, have `invented certain new and useful Improvements in:.Railway SafetyiAppliances,of which the following is a specification.

My invention relates to railway safety i appliances and moreparticularly to devices which operate in conjunction with signalingdevices or semaphores to cut oli' power from a locomotive or other meansfurnishing motion to a train.

The object of this improvement is to provide a simple device of thecharacter mentioned which will effectively cut off the power from atrain or car when the signal ing device is set in a position indicatingdanger, and be in inoperative :positionwhen the signaling deviceis inits clear position. s

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming a part of this specification, and in which,

Figure 1 is a plan view of a broken portion of a railway equipped withmy device, Fig. 2 is an elevation of the same, Fig. 3 is a view taken online 3-3 in Fig. 1, and Fig.` 4 is a section taken on line 4 4: in Fig.1.

The preferred form of construction `as illustrated in the accompanyingdrawing comprises a railway of conventional construction made up ofrails 5 and cross ties 6.a Certain of the cross ties 6 are extended beyond others to afford a base for the signaling and tripping deviceincluded in the construction. Situated on two of the extended ties 6 isan upright post 7 carrying a signaling arm 8 and constitutes a signalingdevice or semaphore now in conventional use. The signaling arm 8 ofthesemaphore is operated by means of a connecting rod 9 which extendsdownwardly through post 7 and connected with one arm of the bell cranklever 10. The other arm of bell crank lever 10 is connected with aconnecting rod 11 which extends to a tower, or other place from whichthe semaphore is operated, not shown. The connecting rod 11 is extended:beyond the semaphore to a tripping device which embodies my invention.This tripping de- Specification of Letters Patent.

vice consists of a stand 12 uponzwhich is secured a head 13. The head13iis provided with an opening in one side through which is slidablymounted a member 14. Said member 14 is provided with a slot15 at itsinner `end and the slot 15 engaged by one arm of a bell crankleverrlll.` Thebellcrank lever 16 is pivoted inhead 13'and has fitsother arm connected by means of a connecting rod 17 with a second bellcrank lever 18 which is pivoted at thelower end of stand 12. The otherarm of bell crank lever 18` is connected with connecting rod 11 in a;

manner to be operated simultaneously with the signaling arm 8 of thesemaphore. Po-

sitioned at about the same distance `from the semaphore as the Signalingdevice already described is a second signaling device made identicalwith the one already mentioned and connected with the connecting link 11in the same manner. The second signaling;`

device is provided so that a train, not shown, running over rails 5 fromeither direction will be operated on by a member 141`at a given distancefrom the semaphore. l.

In the construction shown the connecting rod 11 extends to theswitchman.s tower, not` shown, but it is understood that any form ofmeans may be used to operate the semaphore which is desired. In caseother means are used to operate the semaphore the connectingrods 11 areused to connectthe bell crank levers 1S with bell crank lever 10 inorder to cause simultaiiieous operation of the two tripping devices uponopcrationof the signaling device or semaphore. i

l/Vhile I have illustrated and described the :preferred form ofconstruction for carrying y y my invention into e'fl'ect, this iscapable `of variation and modification without depart ing from thespirit of the invention. I, therefore, do not wish to be limited to theprecise details of construction set forth, but desire to avail myself ofsuch variations and modifications as come within the scope oftheappended claims.

Having` described my invention what I claim as new and dcslre to secureby Letters Patent is:

1. A device of the class described comprising a signaling device; astand positioned at a distance from said signaling device; an elongatedmember slidably mounted in said stand and having one end extending`laterally therefrom and its inner end provided with a laterallyextending slot; a

,. 5 2.1Axdevice of the class described comprising a signaling device; astand' posi tloned atA a dlstancefrom said'slgnallng device.; a powersvvitch4 tripping member slid# ablymounted in said stand and having 'aportion extending therefrom, there being a laterally disposed lslot atthe inner end of said member.; acrank arm journaled in said` i stand andengaging `saidslot; a bell' crank lever pivoted in said stand; aConnecting rod connecting one arm of said bell crank lever 15 with saidcrank arm; and a connecting rod eonnectinggthe other arm of said bellvcrank `lever with said signaling device, substantially as described.

In testimony whereof Iv have signed my 20 name to this specification inthe presence of tivo subscribing Witnesses..` L
